This forum was suggested to me by a fellow member of Gunboards.com I have a small collection that I inherited from a friend. I will keep most of it but that will depend on what fair value is. That has been my focus over the last few months. I came across the rounds pictured below. They are a one piece plastic shell with what appears to be a shotgun primer (209?) They will fit a 38 Spl. chamber and have a 1 or 2 digit number on the rim. It was suggested these are mold marks. Any help would be appreciated. Thank you.
